Question

How can I write repeated multiplication using powers ?

Answer 1

You can put the number you are repeating and then above it put how many times you are repeating it.

Answer 2

`\underbrace{a\cdot a\cdot a\cdot a\cdot ...\cdot a}_(n)=a^n\\\\Examples:\\\\\underbrace{2\cdot2\cdot2\cdot2}_(4)=2^4\\\\\underbrace{3\cdot3\cdot3\cdot3\cdot3\cdot3\cdot3\cdot3\cdot3\cdot3}_(10)=3^(10)`
