Question

if (x^5×x^-2=64,what is x​

Answer 1

Answer:

x = 4

Step-by-step explanation:

x^5 × x^-2 = 64                                                              ( x^m × x^n = x^m+n )

x^( 5 + (-2) ) = 64

x^(5-2) = 64

x^3 = 64

x = ∛64                                                                              ( 4^3 = 64 )

x = 4
