Question

What is 4b to the 4th power when b=3?

Answer 1

4b^4 like this right?

Answer 2

\(\normalsize\color{black}{ (4b)^4=(4 \times 3)^4=12^4=20,736}\)

Answer 3

oh ok

Answer 4

Thanks

Answer 5

either \(\normalsize\color{black}{ (4b)^4=(4 \times 3)^4=12^4=20,736}\)

or

\(\normalsize\color{black}{ 4(b)^4=4 (3)^4=4 \times 81=324}\)

Answer 6

Do you know which one?

Answer 7

I am thinking when they word the problem as 4b to the forth power, it is the first one, because if it was otherwise, then they would have said
" 4 times b to 4th power"

Answer 8

ok thanks

Answer 9

Anytime !

Answer 10

I would use (4b)^4

Answer 11

Nice van, bwt :)

Answer 12

thanks!

Answer 13

What is 4a to the 2nd power - 5b to the 2nd power when a=5 and b=3

Answer 14

\(\normalsize\color{black}{ (4a)^2-(5b)^2}\) \(\LARGE\color{white}{ \rm │ }\)
\(\normalsize\color{black}{ (4a-5b)(4a+5b)}\) \(\LARGE\color{white}{ \rm │ }\)
\(\normalsize\color{black}{ (4(5)-5(3))(4(5)+5(3))}\) \(\LARGE\color{white}{ \rm │ }\)
\(\normalsize\color{black}{ (20-15)(20+15)}\) \(\LARGE\color{white}{ \rm │ }\)
\(\normalsize\color{black}{ (5)(35)}\) \(\LARGE\color{white}{ \rm │ }\)
\(\normalsize\color{black}{ 175}\) \(\LARGE\color{white}{ \rm │ }\)
