Final answer:
This answer explains how to simplify various expressions involving multiplication, addition, and division.
Step-by-step explanation:
a) To simplify 4⁹ × 4³, we can add the exponents together, since the bases are the same. So, 4⁹ × 4³ = 4^(9+3) = 4¹².
b) To simplify 65 × 6², we can multiply 65 by the square of 6. So, 65 × 6² = 65 × 6 × 6 = 2340.
c) To simplify 86 + 8, simply add the two numbers together. So, 86 + 8 = 94.
d) To simplify 7⁹ ÷ 76, we need to divide the two numbers. So, 7⁹ ÷ 76 = 40353607 ÷ 76 = 530163.3553.
