Question

simplify the expression
3squared * 3 to the 5

Answer 1

you mean 3^2 * 3^5
\[ 3^2 \cdot 3^5 \]
one way is expand 3^2 and 3^5
3^2 means 3*3
3^5 means 3*3*3*3*3
so
\[ 3^2 \cdot 3^5 = 3 \cdot 3 \cdot 3 \cdot 3\cdot 3\cdot 3\cdot 3 \]
now write the answer is "short hand" using 3^ exponent

Answer 2

so the answer is 3^7 @phi

Answer 3

yes

Answer 4

if you do that enough times, you realize that you can do a short cut: add the exponents
notice that 2+5=7
