Answer:
[tex] \sqrt{245} \: and \: \sqrt{135} [/tex]
Step-by-step explanation:
When the number is converted back into the radical , the root factor i.e. 2 in first question and 3 in second question is taken as an exponential value and it is powered to the exponent . So , it becomes
[tex] \sqrt{ {7}^{2} \times 5} \: and \: \sqrt{ {3}^{3} \times 5 } [/tex]
[tex] \sqrt{49 \times 5 } \: and \: \sqrt{27 \times 5} [/tex]
[tex] \sqrt{245 } \: and \: \sqrt{135} [/tex]
