Question

$4 \sqrt{81} - 3 \sqrt{343 } + 15 5 \sqrt{32} + \sqrt{225}$
​

Answer 1

Here, as provided question there is some important values missing. Therefore, first we will correct the question and after that will solve this question, let's begin it –

★ CORRECT QUESTION :

Find the value of the given question –

$4 \sqrt{81} \: - 8 \sqrt[3]{343} \: + 15 \sqrt[5]{32} \: + \sqrt{225}$

Now, as per the provided correct question we have to find the value of the given question –

$⟹ \: 4 \sqrt{81} \: - 8 \sqrt[3]{343} \: + 15 \sqrt[5]{32} \: + \sqrt{225}$

Now, we will have to remove the sign of square root and and substituted as per the provided value in the question –

⟼ 81 = 9 × 9

⟼ ³√ 343 = 7 × 7 × 7

⟼ ^5√32 = 2 × 2 × 2 × 2 × 2

⟼ √225 = 15 × 15

Therefore, we have got here the value after removing the square root. Now, we will substitute the value to change into simple form –

[ substituting the values ]

$⟹ \: 4(9) \: - 8(7) \: + \: 15(2) \: + (15)$

$⟹ \: 25$

Hence, the value obtained after solving this question = 25.
