How do i simplify this: ( -9 )^6 * ( x^2 )^1 * ( w^2 )^7

open parentheses minus 9 close parentheses to the power of 6 space cross times open parentheses x to the power of 2 close parentheses to the power of 1 space cross times open parentheses w to the power of 2 close parentheses to the power of 7 Posted in Algebra, asked by Cameron, 6 years ago. 2086 hits.

step 1:

multiply -9 6 times : -9*-9*-9*-9*-9*-9=531441

step 2:when bases are same powers are added in multiplication: (x2 )1  here x is multiplying 1 .So, x2

step 3:(w2 )7 here w2 is multiplying 7 times so, w2 . w2.w2.w2.w2.w2.w2 ( co-efficent will going to multiply 7 times and power 2 is added 7 times)=w14

final step : writing the answer in proper order =531441x2w14  is the answer.

#1: multiply (-9) a/c to its power means 6times = (-9)*(-9)*(-9)*(-9)*(-9)*(-9)*=531441

#2: x2*1 = (x)2*1 = x2  

#3: w2*7  = (w)2*7 = w14

#4: complete answer will b = 531441x2w14
