7(15-10-3) = 7(2)=  49

Answer 2

To solve this mathematical expression, follow the order of operations (PEMDAS/BODMAS):

1. Parentheses/Brackets
2. Exponents/Orders
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Let's break down the expression step by step:

1. First, solve the exponent 7⁵: 7⁵ = 7 * 7 * 7 * 7 * 7 = 16,807

2. Next, square the result of 7⁵: (7⁵)² = (16,807)² = 281,474,976,849

3. Now, solve the exponent 7³: 7³ = 7 * 7 * 7 = 343

4. Finally, divide the squared result by 7³: (7⁵)² : 7³ = 281,474,976,849 : 343 ≈ 821,620,049.

So, 7¹⁵ :( 7⁵)² : 7³ is approximately equal to 821,620,049.
