Answer:

Simplify:- (i) (4²×5- ²) (4²÷5²)

(ii) (1⁰+2⁰+3⁰) ÷ (x⁰+y⁰)

ChatGPT

(i) Let's simplify the expression step by step:

(4²×5-²) (4²÷5²)

First, let's simplify the exponents:

4² = 16

5² = 25

Now, let's substitute these values into the expression:

(16×1/25) (16÷25)

Next, let's simplify the multiplications and divisions:

(16/25) (16/25)

Now, let's simplify the expression inside the parentheses:

(256/625)

Therefore, the simplified expression is 256/625.

(ii) Let's simplify the expression step by step:

(1⁰+2⁰+3⁰) ÷ (x⁰+y⁰)

Any number raised to the power of 0 is equal to 1, so we can simplify the expression:

(1+1+1) ÷ (x⁰+y⁰)

Now, let's simplify the addition:

(3) ÷ (x⁰+y⁰)

Any number divided by 1 is equal to the number itself, so we have:

3 ÷ (x⁰+y⁰)

Since x⁰ and y⁰ are both equal to 1, we can further simplify:

3 ÷ (1+1)

Simplifying the addition:

3 ÷ 2

Finally, let's divide:

3/2

Therefore, the simplified expression is 3/2.

Answer:

• 1. 256 is the answer because (16*-25)=400 and (16÷25)= 0.64 then 0.64*400= 256
