Calculate the value of the following logarithms to the correct significant figures

Log10(8.337)
Log10(8337)
Log10(8.337 * 10E8)
Anti-Log(0.454) = 10^0.454
Anti-Log(1.454)= 10^1.454
Anti-Log(-1.454) = 10 ^-1.454

Thanks!

Calculate the value of the following logarithms to the correct significant figures

Log10(8.337)=0.9210

Log10(8337)=3.9210
Log10(8.337 * 10E8)=0.9210+8=8.9210
Anti-Log(0.454) = 10^0.454=2.844
Anti-Log(1.454)= 10^1.454=28.44
Anti-Log(-1.454) = 10 ^-1.454=0.2844
