Answer:
B
Step-by-step explanation:
Exponents Law:
[tex]a^{m}*a^{n} = a^{m+n}[/tex]
In exponent multiplication, if bases are same, add the powers(exponents).
Write 7.19 in expanded form: 7.19 = 7 + 0.1 + 0.09. Now apply the exponent rule.
[tex]2^{7.19}=2^{7+0.1+0.09}\\\\=2^{7}*2^{0.1}*2^{0.09}\\\\= 2^{7}*2^{\frac{1}{10}}*2^{\frac{9}{100}}[/tex]
