Question

3√27+3√64+3√125 answer​

Answer 1

Step-by-step explanation:

On prime factorising, we get,

125=5×5×5 =5

3

64=2×2×2×2×2×2=4×4×4 =4

3

.

Then,

3

125×64

=

3

5

3

×4

3

=5×4=20.

Therefore, 20 is the solution.

Answer 2

given

3√27+3√64+3√125

$= > {27}^{ \frac{1}{3} } + {64}^{ \frac{1}{3} } + {125}^{ \frac{1}{3} }$

$= > {3}^{3 \times \frac{1}{3} } + {4}^{3 \times \frac{1}{3} } + {5}^{3 \times \frac{1}{3} }$

$= > {3}^{1} + {4}^{1 } + {5}^{1}$

$= > 3 + 4 + 5$

$= > 12$

your answer is 12
