2018年3月6日 · The number of times a term is multiplied is the exponent you use. In this problem 4 is multiplied 6 times. Therefore: 4 * 4 * 4 * 4 * 4 * 4 = 4^6

2018年3月28日 · 4^6*a^4 in 4*4*4*4*4*4*a*a*a*a there are 6 fours and 4 a, so we would raise 4 to the power of 6 and a to the power of 4 4^6*a^4

2018年3月21日 · (x+y)^4 = x^4+y^4+z^4+4x^3y+4xy^3+4y^3z+4yz^3+4z^3x+4zx^3+6x^2y^2+6y^2z^2+6z^2x^2+12x^2yz+12xy^2z+12xyz^2 Note that: (a+b)^4 = a^4+4a^3b+6a^2b^2+4ab^3+b^4 So we can find the terms of (x+y+z)^4 that only involve 2 of x, y, z by combining the expansions of binomial powers, One way to see that …

2016年4月19日 · In the case of #a^4-b^4#, you'll see that #a^4# is just #(a^2)^2# and #b^4# is just #(b^2)^2#: #a^4-b^4=(a^2)^2-(b^2)^2# #=(a^2+b^2)(a^2-b^2)# But as you can see, we can use the formula again: #=(a^2+b^2)(a+b)(a-b)# And this is the final answer

2015年12月19日 · x^4+16x^3+96x^2+256x+256 The fourth row of Pascal's triangle is 1,4,6,4,1 Therefore, (a+b)^4=a^4+4a^3b+6a^2b^2+4ab^3+b^4 This can be applied as follows: (x+4)^4=(x)^4+4(x)^3(4)+6(x)^2(4)^2+4(x)(4)^3+(4)^4 =x^4+16x^3+96x^2+256x+256

2016年10月10日 · a^4+b^4 = (a^2-sqrt(2)ab+b^2)(a^2+sqrt(2)ab+b^2) Notice that: (a^2-kab+b^2)(a^2+kab+b^2) = a^4+(2-k^2)a^2b^2+b^4 So if we put k = sqrt(2) then we find: a^4+b^4 = (a^2 ...

The fish population of lake henry is decreasing at a rate of 4% per year. in 2002 there were about 1,250 fish. write an exponential decay function to model this situation then find the population in 2008?

2015年11月23日 · 4 The given expression is equivalent to log_5 (5)^4 = 4 log_5 5 =4

2016年8月2日 · No, −|−4|!=|−(−4)|. The absolute value of a number is the magnitude of that number regardless of the sign before it. For example, the absolute value of both -4 and 4 is 4. Let's look at the left side of the equation, -abs(-4). The absolute value of -4 is 4. This leaves us with -4 on the left side of the equation. Let's look at the right side of the equation now, abs(-( …

2017年7月4日 · See a solution process below: We can use Pascal's triangle to solve this problem. The triangle values for the exponent 3 are: 1color(white)(.....)3color(white)(.....)3color(white)(.....)1 Therefore (x + 4)^3 can be multiplied as: (1 xx x^3) + (3 xx 4x^2) + (3 xx 4^2x) + (1 xx 4^3) x^3 + 12x^2 + 48x + 64
