I hope this helped I've only done part A
Answer:
Step-by-step explanation:
22/7x7^2=154
22/7x3^2=28(approx)
154-28=126
384 in³
the volume (V) of a cuboid = length × width × height
V = 12 × 4 × 8 = 384 in³ ← fourth on list
9514 1404 393
Answer:
4^4·6^5·7^7 = 1,639,390,814,208
Step-by-step explanation:
Taking the cube root multiplies each exponent by 1/3.
((4^12)(6^15)(7^21))^(1/3) = (4^(12/3))·(6^(15/3))·(7^(21/3)) = (4^4)(6^5)(7^7)
