cube root of 3^6×4^3×2^9/8^6×2^6
Answers
Answer:
9/8 by teacher answer
3 6 1/3*4 3 1/3 * 2 6 1/3 / (8 6 1/3 *2 )6 1/3 cancellation 9*4*8/64*4 44 two fours will get cancelled 8*8=64 so 64 will get 8 answer is 9/8 if you didn't understand then you write simply multiplication and answer
Given,
An expression: 3^6×4^3×2^9/8^6×2^6
To find,
The cube root of the given expression.
Solution,
We can simply solve this mathematical problem using the following process:
Mathematically,
For any variables x, a, and b,
{(x)^a}^b = (x)^(a×b)
{Statement-1}
The cube root of the given expression can be calculated as follows:
(3^6×4^3×2^9/8^6×2^6)^1/3
= {(3^6)^1/3 × (4^3)^1/3 × (2^9)^1/3} ÷ {(8^6)^1/3 × (2^6)^1/3}
= {(3)^6×1/3 × (4)^3×1/3 × (2)^9×1/3} ÷ {(8)^6×1/3 × (2)^6×1/3}
(according to statement-1)
= {(3)^2 × (4)^1 × (2)^3} ÷ {(8)^2 × (2)^2}
= {9 × 4 × 8} ÷ {8 × 8 × 4}
= 9/8
Hence, the cube root of the given expression is equal to 9/8.
