Question

0.13×p^2=13 than p =?

Answer 1

HEYA!!
---------

$0.13 \times p {}^{2} = 13 \\ \\ \frac{13}{100} \times p {}^{2} = 13 \\ \\ p {}^{2} = \frac{13 \times 100}{13} \\ \\ p {}^{2} = 100 \\ \\ p = \frac{ + }{ - } 10$
Hence P can be 10 or -10

Answer 2

0.13 × p² = 13

Multiply the left hand side:

0.13p² = 13

Divide by 0.13 on both sides:

p² = 13 ÷ 0.13

p² = 100

Square root both sides:

p = √100

p = 10

Answer: p = 10
