Question

5.(a) Find
the value of x if 2x - 7X5 X.- 4 =1250​

Answer 1

Answer:

x = -38

Step-by-step explanation:

2x - 7X5 X.- 4 = 1250​

Calculate the product

2x - 35x - 4 = 1250

Collect like terms

-33x - 4 = 1250

Move the constant to the right

-33x = 1250 + 4

Add the numbers

-33x = 1254

Divide both sides by -33

x = -38

Answer 2

Answer:

Step-by-step explanation:

if the question is - 2^( x - 7 ) × 5^( x - 4 ) = 1250

Then, solution :

1250 = 2 × 5 × 5 × 5 × 5

2^( x - 7 ) × 5^( x - 4 ) = 2^1 × 5^4

So, x - 7 = 1

x = 7 + 1 or x = 8

Or

x - 4 = 4

x = 4 + 4 or x = 8

Hence, value of x = 8
