Alanna Brennan · Answer 1

4x is equivalent to 4 * x whereas xto the 4th power means, x times itself 4 times

4 * 2 = 8

2*2*2*2 = 16 bc 2*2=4 and again 2*2=4 therefore 4*4=16

Difference between (4x) ⁴ and x⁴

= (4x) ⁴ x⁴

= 4⁴x⁴

= 256x⁴, x⁴

Evaluate both when x = 2

(4x) ⁴ = 256x⁴ = 256*2⁴ = 256*16 = 4096

x⁴ = 2⁴ = 16.
