Answer:
1. no
yes
yes
2. d¹/³ b is the final answer
Step-by-step explanation:
1. a surd is just an irrational number, so a radical or a never-ending decimal
2.
simplify like we did to the others by distributing the exponent through the parentheses, then combining like terms, and finally combining fractions.
b⁻⁵(cd⁻¹)³ → b⁻⁵c³d⁻³
d(bc²)⁻¹ → d b⁻¹c⁻²
<u> d⁻⁵b⁻⁸ </u> → <u>d⁻²b⁻³ </u> → d⁻²b⁻³c⁻³
b⁻⁵c³d⁻³ c³
<u />
<u>d b⁻¹c⁻² </u> → d b⁻⁴c⁻³
b³c
divide
<u> d⁻²b⁻³c⁻³</u> → d⁻³b
d b⁻⁴c⁻³
positive indices are just positive exponents; it wants you to make the exponents positive. to do that you find the reciprocal, so you turn the negative exponent into a fraction under the number one and get rid of the negative.
d¹/³b
Answer:
9 and 3 are the second pair because 9×3=27 and9×9=81
Are you sure your in elementary school???????????
9.58 = 9 58/100 = 9 29/50
