Question

Evaluate :
$3 {a}^{0} - 1 \div 3 {a}^{0} + 1$
​

Answer 1

$\frac{3 {a}^{0} - 1 }{3 {a}^{0} + 1}$

And we know that a constant raised to the power zero(0) is 1.

Thus,

$= \frac{3(1) - 1}{3(1) + 1}$

$= \frac{3 - 1}{3 + 1}$

= 2/4

= 1/2

Answer 2

Solution:-

$\bf \: 3 {a}^{0} - 1 \div 3 {a}^{0} + 1$

By using exponential law

$x {}^{0} = 1$

We get ,

$\bf \: 3 {a}^{0} - 1 \div 3 {a}^{0} + 1$

$\bf \: 3 \: - 1 \: \div 1 \: + \: 1$

$\bf \: 2 \div 4$

$\bf \: 0.5$

Answer:- 0.5
