Answer 2

The value of 5p-1 = 1264

Given:

2p + 6 = 512

To find:

The value of 5p-1 is

Solution:

To find the value of 5p-1, we need to know the value of p

Given that 2p + 6 = 512

From given expression find the value of p as shown below

⇒ 2p + 6 = 512

⇒ 2p = 512 - 6

⇒ 2p = 506

⇒ p = 506/2

⇒ p = 253

The value of p = 253

Substitute p = 253 in 5p-1

⇒ 5(253) - 1

⇒ 1265 - 1 = 1264  

Therefore the value of 5p-1 = 1264
