Question

simplify these questions of questin no. 7​

Answer 1

Answer:

1st Answer =3

2nd Answer =42

Step-by-step explanation:

0 0 0

1. P+P+P=?

0

P=1

Then A. T. Q

1+1+1=3

0 2 2

2. 1+4+5

0

1=1

2

4=16

2

5=25

Then

A. T. Q

1+16+25=42

Answer 2

Question :

7) Simplify :

i)$\sf{ { P}^{0} + {P}^{0} + {P}^{0 } }$

ii)$\sf{ { 1}^{0} + {4}^{2} + {5}^{2} }$

Answer :

We will simplify both question by Laws of exponents.

i) $\sf{ { P}^{0} + {P}^{0} + {P}^{0 } }$

$\implies \sf{ 1 + 1 + 1 = 3}$

Because $\sf{ {a}^{0} = 1 } \orange \bigstar$

ii) $\sf{ { 1}^{0} + {4}^{2} + {5}^{2} }$

$\implies\sf{ 1+ 16+ 25 = 42}$

Because $\sf{ {a}^{0} = 1 } \orange \bigstar$

Other Laws of Exponents :

• $\sf{ {a}^{m} \times {a}^{n} = a {}^{m + n} }$

• $\sf{ \frac{ {a}^{m} }{ {a}^{n} } = a {}^{m - n} }$

• $\sf{( {a}^{m}) {}^{n} = {a}^{mn} }$

• $\sf{ {a}^{m} \times {b}^{m} = ( ab) {}^{m} }$

• $\sf{( \frac{a}{b} ) {}^{m} = \frac{a {}^{m} }{ {b}^{m} } }$

• $\sf{(ab) {}^{m} = {a}^{m} b {}^{m} }$

• $\sf{ {a}^{ - n} = \frac{1}{a {}^{n} } }$

• $\sf{ {a}^{0} = 1 }$
