Answer:

253,000

Step-by-step explanation:

$10^{5} = 100000$
$10^{4} = 10000$
Plug the above answers in: 2.1 × 100,000 + 4.3 × 10,000
2.1 × 100,000 = 210,000
Plug 210,000 in: 210,000 + 4.3 × 10,000
4.3 × 10,000 = 43,000
Plug 43,000 in: 210,000 + 43,000
210,000 + 43,000 = 253,000

I hope this helps!

Rewrite the radical exponent as a radical

shepuryov [24]

$\bf a^{\frac{ n}{ m}} \implies \sqrt[ m]{a^ n} 
\qquad \qquad
\sqrt[ m]{a^ n}\implies a^{\frac{ n}{ m}}\\\\
-------------------------------\\\\
\left( 5^{\frac{3}{4}} \right)^{\frac{2}{3}}\implies 5^{\frac{3}{4}\cdot \frac{2}{3}}\implies 5^{\frac{1}{2}}\implies \sqrt[2]{5^1}\implies \sqrt{5}$
