Question

10 × 5n+2+25×5n/3×5n+1+10×5n+1​

Answer 1

Answer:

$50n + 2 + 25 \\ = 52 + 25 \\ = 77$

$15 + 1 + 10 \times 5 + 1 \\ = 16 - + 10 \times 5 + 1 \\ = - 6 \times 5 + 1 \\ = - 30 + 1 \\ = - 29$

$77 \times - 29 \\ = - 2233$

So here is our answer

First we have to convert the equation in two parts

then we have to multiple the answers of two parts

like we have multiplied 77×(-29)

= -2233

Answer 2

Solution:

We have 6 = z + 2

⇒ 6 – 2 = z + 2 – 2 (subtracting 2 from each side)

⇒ 4 = z

Thus, z = 4 is the required solution.
