Answer

$35$

Work Step by Step

Solve using PEMDAS (The priority list for solving expressions: Parentheses, exponents, [multiplication, division], [addition, subtraction]. For the operations in the brackets, solve from left to right) $35 \div[3^2 +(9-7)-2^2] + 10\cdot 3 = 35 \div[3^2+2-2^2] + 10\cdot 3 = 35 \div[9+2-4]+10\cdot 3 = 35 \div 7 + 10\cdot 3 = 5+30 = 35$
