Conner and Jana are multiplying (3⁵6⁸)(3⁹6¹⁰).
Conner's Work
(3⁵6⁸)(3⁹6¹⁰) = 3⁵ +⁹6⁸ + ¹⁰ = 3¹⁴6¹⁸
Jana's Work
(3⁵6⁸)(3⁹6¹⁰) = 3⁵.⁹6⁸.¹⁰ = 3⁴⁵6⁸⁰

Is either of them correct? Explain your reasoning.​

Respuesta :

Conner work is correct. Jana work is wrong

Solution:

Given that,

Conner and Jana are multiplying:

[tex](3^56^8)(3^96^{10})[/tex]

Given Conner's work is:

[tex](3^56^8)(3^96^{10}) = 3^{5+9}6^{8+10} = 3^{14}6^{18}[/tex]

We have to check if this work is correct

Yes, Conner work is correct

From given,

[tex](3^56^8)(3^96^{10})\\\\3^5 \times 6^8 \times 3^9 \times 6^{10}[/tex]

Use the following law of exponent

[tex]a^m \times a^n = a^{m+n}[/tex]

Therefore,

[tex]3^5 \times 6^8 \times 3^9 \times 6^{10} = 3^5 \times 3^9 \times 6^8 \times 6^{10} = 3^{5+9} \times 6^{8+10} = 3^{14} \times 6^{18}[/tex]

Given Jana's work is:

[tex](3^56^8)(3^96^{10}) = 3^{5.9}6^{8.10} = 3^{45}6^{80}[/tex]

This is incorrect

The powers of same base has to be added. But here, powers are multiplied which is wrong
