15% of 200 = (15/100) * 200 = 30.

15% of 600 = (15/100) * 600 = 90.

2^3 = 2 * 2 * 2 = 8.

2^5 = 2 × 2 × 2 × 2 × 2 = 32.

25% of 200 = 200 × 0.25 = 50.

By the double angle identity, 2sin(θ)cos(θ) = sin(2θ).

Using the property of exponents, 2^(3x) * 2^(2x) = 2^(3x + 2x) = 2^(5x).

Using the property of indices, a^m ÷ a^n = a^(m-n). Here, 2^4 ÷ 2^2 = 2^(4-2) = 2^2.

Calculating 2^5 = 32 and 3^3 = 27. Therefore, 32 + 27 = 59.

Using the property of exponents, a^m × a^n = a^(m+n), we get 2^(5+3) = 2^8.

2^5 = 32

According to BODMAS, 4 × 2 = 8, so 3 + 8 = 11.

3.5 + 2.8 = 6.3.

3^(2*1) = 3^2 = 9.

Any non-zero number raised to the power of 0 is 1.

3² = 9 and 4² = 16. So, 9 + 16 = 25.

Calculate 3√(27) = 3 × 3 = 9. Then, 9 - 2 = 7.

3√(27) = 3 × 3 = 9.

4^3 = (2^2)^3 = 2^6 = 64.

Any non-zero number raised to the power of 0 is 1.

6 + 4 = 10, then 5 × 10 = 50.

5! = 5 × 4 × 3 × 2 × 1 = 120.

5! = 5 × 4 × 3 × 2 × 1 = 120.

5C2 = 5! / (2!(5-2)!) = 10.

5^(-2) is equal to 1/(5^2) = 1/25 = 0.04.

Using the property of exponents, we have 5^(2 + 3 - 4) = 5^1 = 5.

Using the property of exponents a^m / a^n = a^(m-n), we have 5^(x+1) / 5^(x-1) = 5^((x+1)-(x-1)) = 5^2.

Using the property of exponents, 5^2 * 5^3 = 5^(2+3) = 5^5.

7! = 7 * 6 * 5 * 4 * 3 * 2 * 1 = 5040.

7! = 7 × 6 × 5 × 4 × 3 × 2 × 1 = 5040
