.) (i) Find the value of 'x'such that 1/49×7²x =7⁸​

Answer 1

Step-by-step explanation:

$\frac{1}{49} × 7x² = 7⁸ \\ 7 {x}^{2} = {7}^{8} \times 49 \\ {x}^{2} = \frac{ {7}^{8} \times 49}{7 } \\ {x}^{2} = {7}^{8} \times 7 \\ {x}^{2} = {7}^{9} \\ {x}^{2} = 40353607 \\ \sqrt{ {x}^{2} } = \sqrt{40353607} \\ x = 2401√7$
