Question

Multiply
�ã7/�ã8 �~ �ã24/�ã49 =

Divide
�ã45/�ã81 =

Simplify
7�ã3/�ã5 =

Answer 1

I don't understand the ã symbol. What is the ~ supposed to represent? Multiplication? Better to use * or x' fr that

If ã means "square root, and ~ means multiplication, then
sqrt7/sqrt8 * sqrt24/sqrt49
= sqrt[7/8)*(24/49)]
= sqrt(3/7)
