Which expression is equivalent to 6 Superscript 4 times 6 cubed?
algol [13]

Answer:

(6x6x6x6)x(6x6)

Step-by-step explanation:

6 to the power of 4 times 6 to the power of 2

If a number a is to the power of b, that means a multiplied by itself, b times

eg 4 to the power of 3 means 4x4x4

hence, 6 to the power of 4 (or superscript four) means 6 itself, 4 times

so, 6x6x6x6 multiplied by 6x6
