Solve Square Root Expression: √36 × √49 + 7² × 2

The given expression is: $\sqrt{36}\times\sqrt{49}+7^2\times2$.

First, calculate the square roots: $\sqrt{36} = 6$ and $\sqrt{49} = 7$.

Multiply the square roots: $6 \times 7 = 42$.

Next, calculate the square: $7^2 = 49$.

Multiply the result by 2: $49 \times 2 = 98$.

Finally, add the two results: $42 + 98 = 150$.

Thus, the answer is: $150$.
