Determine the value of the power 1^5

Determine the value of the power 4^7

Determine the value of the power 3^10

Lastly, Which of the powers does NOT describe the number 1024?

A: 4^5
B: 32^2
C: 2^9
D: 1024^1

Q. Determine the value of the power 1^5.

A. 1×1×1×1×1= 1 (obviously)

Q. Determine the value of the power 4^7.

A. 4×4×4×4×4×4×4= 16,384

Q. Determine the value of the power 3^10.

A. 3×3×3×3×3×3×3×3×3×3= 59,049.

Q. Lastly, Which of the powers does NOT describe the number 1024?

A: 4^5

B: 32^2

C: 2^9

D: 1024^1

A. Let's test each of the option :)

= a) 4×4×4×4×4 = 1024

= b) 32×32 = 1024

= c) 2×2×2×2×2×2×2×2×2 = 512

= d) 1024 = 1024

The only option that doesn't describe 1024 is option c : 2^9.

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

regards,  

mrb

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!
