3. 4.3 = sqrt 18 divided by 7
It's better that you write \sqrt{z} instead, not sqrt[z]. If you wanted cube root though, you should write sqrt[3]{z}. The nth root is which is \sqrt[n]{x}.
Given:
Multiply by the multiplicative inverse of 6.5 on both sides:
Multiply by on both sides:
Square both sides (principal of powers):
